Demi Lovato has debuted pink hair, as seen in new photos she shared on her Twitter page.

The pictures were posted late on Thursday, Jan. 23, with the hashtag #NEONLIGHTSTOUR. The 21-year-old pop singer is set to begin performing concerts in cities in the United States and Canada, starting in Vancouver on Feb. 9 and ending on March 30 in Indianapolis. On April 23, she heads to Brazil and will tour South America and Latin America until March 17.

This marks the first all-pink hairstyle Lovato, who has changed her look constantly over the years, has sported publicly.
